Climate of the Past and its discussion forum Climate of the Past Discussions are issued by Copernicus Publications on behalf of the European Geosciences Union, offering the following:

rapid posting of high-quality manuscripts as discussion papers in CPD (preprints) after an access review by an editor;

interactive public discussion (CPD): immediate posting of referee comments (anonymous or attributed) by at least two independent referees, author comments (on behalf of all authors), and short comments by any registered member of the scientific community (attributed) alongside the discussion paper;

permanent archiving and accessibility of discussion papers together with the interactive comments;

post-discussion peer-review completion and final acceptance for CP or rejection;

CP and its discussion forum adhere to high ethical standards which are summarized in the journal's publication ethics. In order to warrant integrity of the published works, Climate of the Past also has a clear policy on competing interests.

Corrections and retractions

CP pursues the following policy for making corrections to its peer-reviewed content:

Modification of a paper: Copernicus Publications reserves the right to replace a *.pdf file if purely technical corrections are necessary (e.g. corrupt file or incorrect bibliographical entry). In such cases, archives and indices are informed. Under no circumstances will the content be changed.

Corrigendum (final-revised papers only): notification of an important error made by the author(s) or by the journal that affects the publication record or the scientific integrity of the published, peer-reviewed work or the reputation of the author or the journal. Corrigenda are represented by a formal online notice. Corrigenda have to be submitted to Copernicus Publications within 3 years from the publication date of the original journal article. Should there be reasons for publishing a second corrigendum within these 3 years, the first one will be substituted by a single new corrigendum containing all relevant corrections.

Corrections to supplements can only be made in exceptional cases (e.g. major errors that compromise the conclusion of the study). The availability of new data is not a reason for the revision of a published supplement. A supplement is a peer-reviewed and integral part of the paper, and hence part of the published record.

Withdrawal after discussion: authors of discussion papers that are not accepted for further review after discussion or where a revised manuscript was not accepted for final journal publication can request a withdrawal. The discussion paper stays online but the reader is notified about the withdrawal.

Retraction: authors or, in specific cases, editors can decide to formally withdraw a published journal article. The article stays online but the reader is notified about the retraction. Such retractions are most often accompanied by an editorial note explaining the background.

Marked as fraud: in the unlikely case that Copernicus Publications is notified that a posted discussion paper or a published journal article turns out to be a fraud, the paper stays online but is formally withdrawn. The reader is notified about the status and fraud papers are always accompanied by an editorial note pointing out the malpractice.
